Do i have Problem with my RWHP ? hey guys
after i break my old engine and broke my supercharger ( F1C )
i went to a Stroker 403 CID
but i think ihave a problem !
my heads are AFR 72 225
my Crank is Callias 4
my Connecting road 6.125
my piston is Wisco +5 4.005
my engine compression is 11.7 with the cometic gasket .051
i asked Patrick G to Custom camshaft for me to shot 200 Wet Nitrous
and i also asked him to give me the camshat with Lop 114
so he gave me Duration 243 247
with lifts 630 630
i took the car to the dyno
and i had 465 RWHP on dyno jet
the car is Corvette 2006 Z51
with Kooks 1/7/8 headers + Zo6 Full exhust
is there is something wrong with the car ?
or the nitrous Cam do that ?
my old engine i tested
with exactly the same package but Difrenet piston which was -15
so i had engine compression 9.7 for the Supercharger
i runned the engine with SC4 camshaft from LS1speed
without a Real tune with 11.5 AFR ( without supercharger ,, just a run to see )
i had 440 !!!!!!!
so moving from 9.7 engine compreesion to 11.7 ,,, are only around 2 RWHP ?
or something is wrong ?

Different motors, different dynos, different combos.
Are you sure on that compression though? I mean im not sure it just sounds funny because my motor has 58cc chambers, -3cc valve reliefs, with .040 gaskets and im at 11.5:1. I guess its just the added stroke.
The numbers do seem a little low for a 403 with a manual trans. Ive seen 402s with smaller cams and budget heads make 500rwhp in F bodies but a vette will make less due to IRS.

I'd hope he's ripping out a lot more than that with a 403 stroker. On the 200 shot I'd be looking for LOW 10s
